Drug-drug Interaction Study of KL1333 in Healthy Subjects

Phase 1

Completed

• Conditions: Mitochondrial Disease
• Interventions: Drug: KL1333; Drug: Flurbiprofen; Drug: Dextromethorphan; Drug: Bupropion; Drug: Midazolam injection; Drug: Omeprazole; Drug: Caffeine; Drug: Repaglinide

• Registration Number: NCT04643249
• Lead Sponsor: Abliva AB

Brief Summary

A Phase I, Open-label, Fixed-sequence, Crossover, Drug-drug Interaction Study to Investigate the Inhibition Potential of KL1333 on CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in Healthy Subjects

Detailed Description

This will be a Phase I, open-label, fixed-sequence, crossover study to investigate the effect of coadministration of KL1333 on the PK of repaglinide, caffeine, omeprazole, midazolam, bupropion, dextromethorphan, and flurbiprofen in healthy male and female subjects. Potential subjects will be screened to assess their eligibility to enter the study within 28 days prior to the first dose administration. Subjects will be admitted into the clinical research unit (CRU) on Day -1 and be confined to the CRU until discharge on Day 19. Subjects will return to the CRU for a follow-up visit 5 to 7 days after the last dose.

2. Weight ≥50 kg and body mass index between 18.0 and 32.0 kg/m2, inclusive.
3. In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital nonhaemolytic hyperbilirubinaemia [eg, suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at screening and check-in as assessed by the investigator.
4. Females will not be pregnant or lactating, and females of childbearing potential and males will agree to use contraception as detailed in Appendix 4.

Exclusion Criteria

1. Significant history or clinical manifestation of any metabolic, allergic, dermatological, hepatic, renal, haematological, pulmonary, cardiovascular, gastrointestinal, neurological, respiratory, endocrine, or psychiatric disorder, as determined by the investigator.
2. History of significant hypersensitivity, intolerance, or allergy to any drug compound, food, or other substance, including KL1333 or its excipients, unless approved by the investigator.
3. History of gastroesophageal reflux disease, gastric erosions, peptic ulcer disease, or gastrointestinal bleeding episodes.
4. History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs including cholecystectomy (uncomplicated appendectomy and hernia repair will be allowed).
5. History of malignancy of any organ system other than localised basal cell carcinoma of the skin, treated or untreated, within 5 years prior to screening, regardless of whether there is evidence of local recurrence or metastases.
